SPI chip select inputs (active low)
There are 3 SPI chip select inputs:
–
–
–
HOST_INT output (active low)
The SN260 ZigBee processor generates an interrupt to the host processor (STR912xx)
on the falling edge of HOST_INT. This signal is connected to P45 pin on the STR9
dongle which must be configured as an input with interrupt capability.
WAKE_UP input (active low)
This input performs the wake up of the SN260 ZigBee processor. It is connected both
to P55 pin of the STR9 dongle and to B22 button.
–
–
SPI_SEL0: this input is used to select the ZigBee module. It is connected to P80
pin of the STR9 dongle.
SPI_SEL1: this inputs is used to select the MEMS. It is connected to P81 pin of
the STR9 dongle.
SPI_SEL2: this input is used to select the external device if any. It is connected to
P82 pin of the STR9 dongle.
If P55 is configured as an output, the ZigBee device can be woken up either by
a falling edge on the signal connected to P55 pin or by pressing B22 button.
If P55 is configured as an input with interrupt capability, a falling edge on the signal
connected to P55 wakes up the ZigBee device and an interrupt to the STR9
dongle is generated by pressing B22 button.
